166MHz Serial to Wifi Module External Antenna Version Ultra Low Power Consumption USR-C215b Geekcreit for Arduino - prod

Introduction:The module hardware integrates a MAC, a baseband chip, a radio frequency transceiver unit, and a power amplifier;Built-in low-power operation mechanism can effectively achieve low-power operation of the module;Support WiFi protocol and TCP/IP protocol, users can realize the networking function of UART device with simple configuration.Small in size and easy to assemble on the hardware board circuit of the customers product. The specific dimensions are: 22.0mm x 13.5mm x 9.2mm, single row 1x10 2mm pin package.Basic functions:It can work in AP mode and wait for other WIFI devices to access communication. It can access 3 sta at the same time, or it can work in STA mode and access wireless router to realize communication.It has a Socket communication link, which can be set to TCP Server, TCP Client, UDP Server, UDP Client communication; the Socket can support up to 5 TCP Client accesses in TCP Server mode.The module supports UART transparent transmission and can be switched at will using the AT command.FeaturesUSR-C215Number of serial ports1Main frequency166MHzBaud rate1200-460.8KAntennaExternalAP mode access STA3AP+STA mode access STA3Transverse horizontalTCPS/TCPC/UDPS/UDPCSmartlinkSupportSynchronous serial port baud rateSupportAirkissSupportSerial heartbeat packageSupportCustom webpageSupportNetwork time acquisitionSupportThe serial port wifi module C215 supports transparent transmission mode, AT command mode and HTTPD client mode for data transmission, and is suit
